    There's been a lot of fun, practical work recently on optimal join algorithms! (Full disclosure, this advisor on this paper is one of Andy and my former students, so I'm slightly b…

    It's disjointed? The post that started this sub-thread asked: > 1. How many total problems were given to the model, and what percent were left unsolved at what cost before giving u…

    This seems very unlikely compared to the obvious answer that they added a crappy antenna to keep their BoM and assembly costs low. The radios on these are weak and adding an Omni a…

    This isn't really about delivering - it's more about helping to understand the shape of problems that AI can solve right now. If they took 1000 problems and threw the model at it a…

    The mining datacenters beat the AI datacenters to the punch on that, actually: https://www.wsj.com/world/americas/bitcoin-mining-noise-driv...

    The people to whom you are responding were talking about the lack of details in this article about the Guinness "trick", not the ketamine.

    I'm close to DIYing it also. I have two of the la crosse clocks. One works well. The other consistently fails to update. It would be cheaper to buy a new one to see if it's a dud o…

    It's probably not. I tried to extract the commit hash from the version of bun packaged in claude code. the commit hashes from previous versions resolve, whereas the commit hash for…

    I used it for a bunch of remote monitor boxes to have a way of centrally managing ssh access to things that were often on- and off-line. It was simple and convenient and access was…

    Intriguing. I should benchmark my dust-gathering-stack of Titan V's, unless someone already has?

    I had meta's crawler hitting the pi searcher at something like 5qps for days on end, just ... querying for substrings of pi, ignoring robots.txt, etc. it wasn't enough to break any…

    I'm not sure it's about overworking as much as stress - stress is a known potential trigger for manic episodes. Typically in people who already have some biological potential for e…

    Russia's inability to have a decisive victory against Ukraine is at odds with the idea that it has sufficient stockpiles and launch capability to reduce kiev to rubble any time it …

    I think you're over-estimating the capability of both sides of the fight (absent nuclear weapons on the part of Russia). Both sides appear to be using drones and missiles as fast a…

    I'm a little puzzled: Why should you care? The language in which Bun is written isn't part of its API, if you will. You care that you have something that does various javascripty t…
